La Cornue cookers are hand-built to last generations, and they are worth keeping alive. We are an independent Littleton service company that diagnoses and repairs La Cornue ranges and ovens with the patience these machines demand.
Understanding the machine is the first step to fixing it correctly.
A La Cornue is not a mass-produced appliance. Each range is assembled largely by hand in France, and the signature feature is the vaulted convection oven cavity, a rounded roof that circulates heat around food instead of blasting it from one element. That geometry, the heavy enameled steel, the brass or chrome trim, and the modular burner top all mean that a La Cornue behaves nothing like a standard slide-in range on a diagnostic bench.
Because these cookers are meant to run for decades, most problems we see are wear items on an otherwise sound machine rather than a failed appliance. A tired thermocouple, a worn oven gasket, a spark igniter that no longer catches, or a gas regulator that drifted out of spec are all repairable. The frame, the cavity, and the cast burners usually outlive everything bolted to them, which is exactly why owners repair rather than replace.
If your range is doing any of these, it is a repair, not a reason to give up on it.
Littleton sits at roughly 5,350 feet, and thinner air changes how a gas range burns. A La Cornue tuned at sea level in France or set up by a big-box installer will often run rich here, leaving soft yellow flames, soot on cookware, and an oven that never quite hits temperature.
We check the gas regulator, adjust burner air shutters, and verify the oven thermostat against a calibrated thermometer so the flame burns lean and clean at Front Range altitude. This is routine for us and easy to miss for a technician who only works closer to sea level.
A predictable, no-surprises process from the first call to the finished repair.
Call (720) 903-2603 (answered 24/7) or use our online scheduling page. Tell us the model and what it is doing so we arrive prepared.
We come to your home, daily 8:00 AM to 6:00 PM, for a flat $89 diagnostic service-call fee that is credited toward the repair.
You get the actual cause and a firm price before we touch anything further. Any figure quoted in advance is a starting estimate; the final price is set after inspection.
We fit OEM-quality, factory-specified parts, recalibrate for altitude, and confirm the range holds temperature and lights cleanly before we leave.
You should know exactly who is working on your range.
We are an independent appliance-repair company serving Littleton since 2014. We are not authorized, certified, or affiliated with La Cornue or any manufacturer, and we will never claim to be. What we offer instead is straight talk, an owner who answers questions, and technicians who treat a hand-built French range with the same respect you do. If a repair does not make sense, we will tell you plainly rather than run up a bill.
Quick Answers
Littleton Appliance Repair is an independent service company that repairs La Cornue ranges and ovens throughout Littleton and Southwest Denver. We are not affiliated with or authorized by La Cornue, but we specialize in servicing hand-built French cookers. Call (720) 903-2603, answered 24/7, to book a visit.
The diagnostic service-call fee is a flat $89, and it is credited toward the cost of the repair if you go ahead. Repairs are priced after an on-site inspection, so any figure quoted over the phone is only a starting estimate until a technician sees the range.
Almost always. A La Cornue is hand-built to run for decades, and most problems are wear items like gaskets, igniters, thermocouples, or a regulator that needs recalibration rather than a failed appliance. The heavy cavity and cast burners typically outlast every serviceable part, which is why owners keep them running.
FAQ
Anything else — call any hour, a real person answers.
Usually not. Uneven baking in the rounded convection cavity is most often a thermostat that has drifted, a worn door gasket letting heat escape, or an oven that was never calibrated for altitude. We measure actual cavity temperature and correct the cause rather than assume the oven itself has failed.
A burner that sparks but will not light typically has a fouled or cracked spark igniter, a burner cap that is not seated flat, or an air shutter that is out of adjustment for our thin Front Range air. All three are common, inexpensive fixes we handle in a single visit.
In most cases, yes. We source OEM-quality, factory-specified replacement parts for igniters, thermocouples, valves, gaskets, and trim. Because these ranges are built to last, replacement components are generally still available, and we will confirm availability for your specific model when we diagnose it.
We serve Littleton and the Southwest Denver foothills, including Ken-Caryl, Columbine, Chatfield, Roxborough Park, and the surrounding Southwest Denver metro within roughly a 25-mile radius. Service visits run daily from 8:00 AM to 6:00 PM.

Our built-in Sub-Zero was keeping the freezer fine but the upper fridge zone was sitting around 55. Turned out to be the dual-evaporator setup, exactly what the tech guessed on the phone. Brian had the sealed system diagnosed the first visit, ordered the part, and had us back to normal within the week. He didn't try to sell us a new unit like the last place did.
One of the dual-stack burners on our Wolf range would click and click but never light. He mentioned it's common up here because the burners need to be calibrated for the altitude, which no one had ever told us. Relit perfectly after and he adjusted the others while he was at it.
Fixed our Sub-Zero the same week we called. Fair price, no upsell.
Our dual-zone wine cabinet had drifted so the bottom zone wouldn't hold temp and there was condensation collecting on the glass. They diagnosed it quickly but the part had to come from the manufacturer and took about four days, so we were without it for most of a week. Once it arrived the fix was solid and both zones are holding right where they should. Worth the wait, just be ready for the parts delay on these.
Miele dishwasher wouldn't drain, standing water in the bottom every cycle. Bad drain pump. In and out in about an hour and he cleaned out the filter housing that was part of the problem too.
The door gasket on our 15-year-old Sub-Zero had gotten brittle and it was sweating around the seal. New OEM gasket and it seals like new again. Appreciated that they used the factory part instead of some universal thing.
Thermador wall oven quit heating right before we were hosting. Called in the morning and they got someone out that same afternoon. Bad igniter. He had the part on the truck and we still made our dinner.
Ice maker in our Sub-Zero was making cloudy hollow cubes and barely any of them. He flushed the system, replaced a valve, and now it actually keeps up when we have people over. Nice guy, wore booties in the house without being asked.
Solid work on our Bosch dishwasher, the drain pump had failed. The only thing is the $89 service call fee felt a little steep before I knew they credit it toward the repair. Once I proceeded it came off the bill, so no real complaint, just wish I'd understood that up front.
Our Viking freezer was building up a wall of frost and not defrosting on its own. Turned out to be the defrost heater. Fixed it and explained what was going on so I understood why it happened.
Two burners on our Wolf cooktop wouldn't spark. Tech recalibrated them for the elevation and swapped the igniters. Works better than it has in years honestly.
Warm upper zone on our Sub-Zero, classic apparently. They knew exactly what it was, ordered the evaporator part, and came back to install it a couple days later. Honest and easy to deal with the whole way through.
Not many people around here will even touch a Gaggenau. These guys did, got the control board sorted, and were straight with me about the cost of the part on a unit this expensive.
Miele steam oven throwing an error and shutting off mid-cook. The tech was great and clearly knew the unit, but he ran about 40 minutes behind the window they gave me and I had to shuffle some things around. Fixed it in one visit though and it's been perfect since, so I'd still call them again.
Had them out for our built-in outdoor grill that wasn't lighting evenly. Didn't expect them to do outdoor units but they did and dialed it in for the altitude. Grilling season saved.
Quick, clean, and they answered when I called at 9pm the night before. Dishwasher's draining again.
This was a big one, the sealed system on our Sub-Zero failed and that's a job a lot of shops won't take on. They did it right, used factory-spec parts, and stood behind the work. Given it's a $12k built-in I'm glad I found someone who actually knew these inside and out instead of just replacing the whole fridge.
Wine fridge kept fogging up on the door and the temp was bouncing around. Fixed same visit and no more condensation.
